Police are reminding dog-walkers to take extra care of their dogs when around livestock.
This comes after two sheep were viciously attacked by a dog on Dent Fell in Cleator Moor on Wednesday 28 June, late in the evening.
The sheep were later put down due to the injuries they sustained. Both sheep had lambs, which police say may now struggle to survive.
A dog worrying livestock can be a criminal offence and it is the responsibility of the person or owner to control their dog.
Anyone with information is advised to call PC 2101 Mackenzie on 101 or email firstname.lastname@example.org. Crimestoppers can also be contacted anonymously on 0800 555 111.
